Carl and Cesar, with help from the Triads, later kill T-Bone Mendez on Pier 69, before Carl chases and kills Ryder. Carl also seemingly kills Mike Toreno, who had escape using the helicopter as a decoy. Toreno, revealing himself to be an undercover agent, employs Carl to steal a tanker full of fuel on its and tells Carl to use Cesar to help him but not to tell him of Toreno's involvement.

Cesar and Kendl, enjoying the ambience of San Fierro, decide not to join Carl when he begins working for Toreno in Tierra Robada.

Cesar and Carl steal two vehicles from Otto's Autos in Downtown, San Fierro. Cesar and Carl also work together to steal a Jester being loaded on to a cargo ship in Easter Basin.

The residents of the poorer neighbourhoods of Los Santos, including El Corona, begin to riot, with Carl using the opportunity to claim back territory for the Grove Street Families. Carl also later helps Cesar, Gal, Hazer and Sunny to take back El Corona from the Los Santos Vagos. Shortly before the five take back the El Corona, Cesar asks Carl to talk to Sweet about his plans to propose to Kendl, knowing that Sweet had not trusted him.
